These Hubble Space Telescope images, taken by the Advanced Camera for Surveys, reveal Pluto, its large moon Charon, and the planet's two new candidate satellites. Between May 15 and May 18, 2005, Charon, and the putative moons, provisionally designated P1 and P2, all appear to rotate counterclockwise around Pluto. P1 and P2 move less than Charon because they are farther from Pluto, and therefore would be orbiting at slower speeds. P1 and P2 are thousands of times less bright than Pluto and Charon. The enhanced-color images of Pluto (the brightest object) and Charon (to the right of Pluto) were constructed by combining short exposure images taken in filters near 475 nanometers (blue) and 555 nanometers (green-yellow). The images of the new satellites were made from longer exposures taken in a single filter centered near 606 nanometers (yellow), so no color information is available for them.

Personally I think they're a little to liberal in what they're calling moons for Pluto. The planet travels a pretty eccentric orbit in a rough neighborhood. The rocks that are orbiting the planet this plutonian year many not be there next time around.

"That's no moon..."

[JustDoItAlways]

There have never been photos of Pluto that are anywhere near this sharp.

What kind of filtering was done?

If they are real (as in I have my doubts) then we should use this flitering software on every deep-space capture from now on.

[skinkinthegrass]

WOW! ...you said it, very clear.
Its' getting crowded in this solar system. :D

[aMorePerfectUnion]

There must be a mistake. Pluto, like most dogs, would
only have two "moons"... [um, never mind]

[Mr. K]

I thnk it would be a damm shame to abandon Hubble.

What is the cost to keep a team running it and keep it repaired?

How much to replace it- geez we got some great stuff from hubble

[KevinDavis]

Going out in style...

[JustDoItAlways]

Hubble needs to be upgraded and repaired through Spacewalks from the Shuttle. The gyros and back-up gyros themselves are almost ready to give it up and need to be replaced for example.

Given we don't know how safe the shuttle is now and given the limited number of missions that will be carried out now with the Shuttle given it's safety risk, Hubble upgrades don't rank that highly.

Not including those points, there is better technology available today for a space-based telescope, including ability for more detailed pictures but also on more wavelengths than Hubble.

It might be better to spend a billion dollars on several new and better space telescopes and let Hubble crash into the sea than to spend the same dollars on repairing it.

I seem to have fallen off of your Ping list. Please add me to the list again. Thanks!

"let Hubble crash into the sea"

How about Tehran or Damascus?

[Darksheare]

Let me just say this first: This is NOT my fault.

That said, science ping.
Cool stuff.

[Darksheare]

Science ping.
And it isn't my fault.

[SunkenCiv]

Captures. :') At Pluto's distance from the Sun, it's easier for Pluto to grab something because it has a larger sphere of influence than the Earth. (':

[sweetliberty]

"And it isn't my fault"

Uh huh....

[Darksheare]

Wonder what they will finally call these new possible moons.
